MPCA Air Quality Dispersion Modeling Practices Manual – draft available for review

The Minnesota Pollution Control Agency (MPCA) is providing a redline copy showing proposed changes to the MPCA Air Quality Dispersion Modeling Practices Manual (Manual) for the 2017-2018 year. The proposed changes to the Manual this year largely reflect the new Appendix W revisions and clarification of some additional modeling practices. We have posted the draft Manual on our website for you to inspect prior to finalizing the document later this summer.  Input received prior to July 15, 2017 will be taken into consideration before the final version of this year’s manual is posted.

If you have questions or thoughts you would like to share about the proposed changes in the Manual, please contact us directly at, or attend the annual summer Air Quality Dispersion Modeling Open House on July 13, 2017, at the MPCA St. Paul office (520 Lafayette Rd. N.). If you plan to attend the Open House, please let us know by emailing us at A draft agenda will be provided in mid- to late-June. We look forward to hearing from you!
